STOVE OR FU RNACE.

SPECIFICATION forming part of Letters Patent No. 508,474, dated November 14, 18.93.

Applicationlled January 28, 1893. Serial No. 460,024. (No model.)

To all whom, t may concern:

Be it known that I, HARRY C. HoENIsH, a citizen of theUnited States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Stoves or Furnaces; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as -win enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in stoves or furnaces of that class in which gases of whatever origin or nature `may be used and also in which electricity may be used and by which the electric heater may be used after re-` moving the gas burner.

The object of the invention is to provide a stove or furnace in which a larger surface of metal is presented to the heating agent than in any other stove or furnace yet devised and thusl getting a greater amount of heated air from the same amount of fuel used in any other device of this class.

In the appended drawings, Figure 1 represents a sectional .elevation of the stove. Fig. 2 represents a plan view of the stove through dotted line .fr a: Fig. l. Fig. 3 is an elevation of a portion of the lower end of the stove.

In the several ligues, A represents the outer casing of the stove which is made of any suitable material and of any suitable height and diameter, and which is surmounted by a top plate B, provided with an escape pipe C. The lower portion of said casing flaresl outwardly at A and forms the larger body or drum A2 and this drum drops perpendicularly for some distance and is provided with the bottom A3 mounted on legs A4. With the bottom A3 is made a depending ange or collar D, located centrallyand which is open at the bottom as shown. A gas burner E of the usual construction for such stoves is placed within this depending flange D and is held therein by resting upon one or more rods F F Figs. l and 2. The top of the burner E projects somewhat above the bottom A5 and a deliecting plate G forming the bottom of a hot air chamber H is located directly above said burner and is sustained in place by any suitable means. This hot air chamber is made in any convenient shape desired; the one shown however is circular in form, its intetaining the heat. 'is not entirely closed, but has openings into rior' surfaces, upper and lower, being parallel one with the other except the central portion of the bottom' which drops into a depending basin and the said bottom forming the de.

ilectin g plate G is made of considerable thickness immediately over the burner and both the inner and lower surfaces of said plate are provided with a number of heavy lugs for re- The air chamber however which upper and lower pipes I and J are inserted in the top andbottom plates respect.- ively of said chamber.

As shown in Figs. 1 and 2 the upper ends of the pipes J open into the bottom of the chamber H, and thelower ends of same pass through the bottom A3 of the stove, thus forming an opening from the outer air through the said bottom A3 and pipes J into the said air chamber. These pipes .I are set in two continuous circular rows, each pipe of a row being equidistant from the center of the stove, and each pipe of the series of pipes of the outer row being set back of, and between the pipes of the inner row, as may be understood by reference to Fig. 2. I do not restrict myself however to two rows of pipes only but one or more rows may be employed satisfactorily.

The upper pipes I are let into the upper plate of the hot air chamber as before stated, and being the same in number as the lower pipes J, may be set immediately over the said lower pipes to form a direct unbroken passage from Vthe pipes J to the pipes I, or the upper series of pipes I may be set around slightly to bring the pipes of.' each tier out of the direct line to cause more heat radiation.

The upper and lower ends of each of the vertical pipes of the stove are provided with annular anges a a either to allow the pipe torest upon a portion of the stove, or for the pipe to support a portion thereof. The upper ends of the pipes I support a second hot air chamber K. This chamber is circular in form and of such diameter as to tit snugly within the casing A, and the top and bottom of which are parallel as shown,`and the center portion of this chamber is cut out top and bottom, but closed within itself, to form the opening K for the passage of heat. This box -or chamber then is merely a closed hollow IOO casing A. Then a fourth series of pipes L2- opens into this chamber at the top and support at their upper ends a fourth chamber M of the saine shape and fitted the saine as the chamber K and this is succeeded by the scries of pipes M2, the chamber N with its depending basin N', of the same size, form and location as the chamber L and this chamber N is succeeded by the pipes N2 which pass through the top B. These ends of the pipes N2 are flared to fit the openings in the top by fitting and driving in the wedge shaped rings or collars N3 having the projecting lips N4.

The casingA is enlarged at the bottom into the drum A2 for the purpose of admitting the pipes O from the bottom A2 which is an extra series of pipes set outside of the pipes J as shown in Figs. 1 and 2, to conduct air from the outside into the air chamber H. The said pipes O open into the horizontal pipes P which connect the chamber H with the outer casing of drum A2. Thus it will be seen that air may be taken either from the room through pipes Pand regulated by au ordinary damper P or the air may be 'taken in from the outside air through the air conduit Q through the pipes O. The pipes O and P may be also put in separately as desired. The said air conduit Q is secured by any good means to the bottom of the stove or furnace and which incloses the entire bottom thereof and leads to the outer air and this of course furnishes pure air and plenty of it to be heated. The said conduit is provided with doors Q through which may be taken the air from the rooms to be heated. Now the burner being of a less diameter than the depending flange D, the air may easily get to the burner through the passage D thus left, and thereby giving said burner a perfect draft. The draft thus given may be perfectly regulated by the following meansz-A funnel R is hung from the flange D by the before mentioned rods F and the neck of the funnel is elongated into the pipe S which is carried up to a dainperT cast with the lower portion of the stove. This damper is of ordinary form simply being a plate with the holes made therein and closed or opened by a pivoted swinging plate tocorrespond therewith. The rods F pass through holes drilled through the funnel and the ilange D and split pins are inserted in holes in either ends of said rods to keep them in place, so that when it is desired to take out the burner the rods are simply withdrawn and the burner can be quickly removed. An opening is made in the flange D and a door D2 is hungto admit the hand to the burner. A pipe shown byE leads from the fuel supply to the burner. A number of doors A5 are located around the drum A2 for taking air in if desired: The lower portion of the drum portion A21s provided with a series of holes U near its bottom and a collar V (Fig. 3) (shown raised) is placed over them and is provided with holes W corresponding with the holes U. The collar rests on a flange X on the bottom of the drum and is provided with a wing or a lug to assist in the operation of saine..

For using as a furnace, an auxiliary casing is made to envelop the device described and from that casing pipes lead to different roomsk to be heated.

The operation of the device is as follows:-

The oil, gas or whatever fuel is used maybe admitted to the burner and the burner Vis lighted through the door D2 in the flange D and the flame from the burner impi'nges on the detlecting plate and the plate being thus heated throws its heat from the interior of the chamber H up through the pipes above and mixing with the hot air from the other chambers passes ont into the room. The heat from the flame and bottoni side of the deflecting plate passes outward and toward the .casing A2 passing and impinging upon the pipes O and P and J and thence up between the outer casing and the chamber H thence back toward the center of the stove between the pipes I I and through the central opening K' in the air chamber K, thence outwardly again between the pipes K2 and between the chamber L and casing A then toward the center again and up and so on to the escape pipe C. As the heat from the burner passes between the series of pipes and under the series of hot air chambers the said pipes and chambers are heated to a very great extent, and by the time said heated air from the burner reaches the escape pipe, it has lost its warmth in heating the pipes and chambers before mentioned.
